Abstract

The utility model discloses a dredging sediment diversion dam which is a river dam and has the functions of depositing the sediment of the river in a water storage sediment diversion area, supplying the river water to the artificial sightseeing lake as the landscape belt through a water inlet and ensuring the water flowing in the artificial sightseeing lake to be clear. A dam body of the dredging sediment diversion dam is connected with a segregation dam, the dam body extends and closes to one side of an upstream retaining dam firstly in a linear shape and then in an S-shape against the water flow direction till the dam body is connected with a river embankment; the dam body is provided with a water inlet close to the retaining dam; and the upper edge of the water inlet is parallel and level to that of a waster storage dam. The dredging sediment diversion dam is built at the upstream of the water storage dam and the first-class retaining dam and is connected with the segregation dam. The dam has the functions of accumulating the river water with the sediment in the water storage sediment diversion area, depositing the sediment in the water storage sediment diversion area, supplying the deposited clear water to the artificial sightseeing lake and ensuring the lake water to be clear without large quantity of sediment deposition.

Description

Desilting divides sand bar
Technical field
The utility model relates to the river dykes and dams, specifically is that required desilting divides sand bar when building rubber dam landscape band on the river course.
Background technology
At present, urban construction is maked rapid progress, and in order to create a good days environment to the common people, much has the city of river process and area to build rubber dam landscape band.The river that silt is less seals whole riverbed with rubber dam, form artificial lake landscape band; The river that silt is more is divided into two the riverbed, and small part is artificial lake for the canal that drains off floodwaters is most of, and artificial lake is gone sightseeing for the visitor.But this rubber dam landscape band that the riverbed is divided into two is arranged in desilting at present and is had more problem aspect husky: mainly be that storage dam and one-level, the sedimentation of secondary check dam are too many, neither attractive in appearancely also be not easy to desilting and maintenance.
The utility model is that a kind of desilting divides sand bar, can effectively overcome too many drawback and the defective of existing rubber dam landscape band silt alluvial.
The utility model content
Rubber dam landscape band for the more area build of river silt, be provided with one or more levels check dam, built isolation dam in the riverbed, the riverbed is divided into two parts: manually the go sightseeing lake and the canal that drains off floodwaters, isolation dam, check dam and river levee form artificial sightseeing lake together, isolation dam and opposite side river levee form the canal that drains off floodwaters, drain off floodwaters the width of canal much smaller than the width in artificial sightseeing lake, built storage dam with one-level check dam corresponding position, the build desilting that links to each other with isolation dam divides sand bar, described desilting divides sand bar to be made of dam body and water inlet, its dam body flow path direction against the current earlier upstream extends to the position, riverbed that one-level check dam top water level can reach with linear, afterwards with the S type upstream check dam one side draw close, end is connected with check dam one side river levee, and dam body and river levee join to holding and be abutment, and the end that links to each other with isolation dam is the dam tail, dam body is provided with water inlet in one-level check dam upstream, and the upper edge of water inlet is concordant with the storage dam upper edge.
The beneficial effects of the utility model are as follows: 1, desilting divides sand bar with the poly-retaining Fen Sha district that stays of upland water, make the sediment deposition of being with in the river, treat that water level rises when reaching the water inlet, water has been clarified and has been begun to flow into artificial sightseeing lake, realized that desilting divides husky purpose, the river that guarantees to enter artificial sightseeing lake is as clear as crystal; 2, put things right once and for all, the long-term assurance do not have a large amount of silts to enter artificial sightseeing lake, do not need frequent desilting row husky, saves human and material resources, reduced maintenance cost.
Description of drawings
Fig. 1--rubber dam landscape band and desilting divide the sand bar floor map
Fig. 2--rubber dam landscape band cross sectional representation
The drawing explanation:
Among Fig. 1: position, the riverbed 8-one-level check dam 9--that 1-water (flow) direction 2-river levee 3-storage dam 4-retaining Fen Sha district 5-dam body 6-riverbed 7-one-level check dam top water level can the reach lake 10-isolation dam 11-water inlet of manually going sightseeing
Among Fig. 2: the 2-river levee 9-lake 10-isolation dam 12-canal that drains off floodwaters of manually going sightseeing
The specific embodiment
Below in conjunction with description of drawings the utility model specific embodiment:
Shown in Figure 2 as Fig. 1, rubber dam landscape band comprises river levee 2, storage dam 3, one-level check dam 8, manually go sightseeing lake 9, isolation dam 10, the canal 12 that drains off floodwaters, water (flow) direction 1 indicates the flow direction of river.Desilting divides sand bar to be made of dam body 5 and water inlet 11, dam body 5 links to each other against the current, and flow path direction upstream extends to the position, riverbed 7 that one-level check dam top water level can reach with linear earlier with isolation dam 10, afterwards with S shape upstream check dam one side draw close, end is connected with check dam one side river levee, this end is abutment, the end that links to each other with isolation dam 10 is the dam tail, and abutment exceeds riverbed 6 and is 100-200CM, and the dam tail exceeds storage dam 3 upper edge 50-100CM.Dam body 5 is provided with water inlet 11 in one-level check dam 8 upstreams, the upper edge of water inlet 11 is concordant with storage dam 3 upper edges, the distance of water inlet 11 and one-level check dam 8 is 1/3 place of distance between one-level check dam 8 and the one-level check dam top water level position, riverbed 7 that can reach, and the aspect ratio of water inlet 11 is 5: 1.The straight line portion of dam body 5 is the reinforced concrete structure, and width is identical with isolation dam; Sweep is for being the trapezoidal cement structure of gravel and sand.
